Design, simulation and test of a cavity in the UHF band
Résumé
A simple and successful design for a UHF cavity is presented with a rejection factor inferior to -47dB for a difference of 1.6MHz between the transmit frequency and the receive frequency, the insertion loss being less than 1dB. A coil connected to the resonator ensures a 50 adaptation. A modelization of the device, based on the Pspice software, is described.
